CYKLOPS is an excellent model for testing visualization and retinal laser systems. The anterior segment of the model features a color wheel that enables testing of color rendition in digital (3D) systems. The posterior segment has a special coating that provides an intense red reflex and is sensitive to (Green) laser treatments, allowing for the practice of Endolaser treatments. CYKLOPS shares the same visualization optics as our FUNDUS model, allowing visualization with indirect, contact, and non-contact visualization systems.
